Maybe you should take a look at the MessageMap of your tabcontrol!?

Combo Box vertical scroll bar height

Hi
Is there a way of setting the height of vertical scroll bar in a
Combo box?

i.e., even if there's only one item in the Combo, is
it possible to set the height of vertical scroll bar?

What i have seen is, if there's only one item, the vertical scroll bar
is very small or not at all scrolable. I would like to set it a little
longer so that its scrollable.

Thanks

Socket details using PID

Is there a way to tie a network connection to a PID (process ID) using Windows Socket functions? I would like to find network connection details associated with a particular process; more specifically in the process, port at which socket is listening and connection state I need to find. Any Windows Socket functions avialable to fetch all these details using VC++?

TIA!

It's not part of Winsock, but there is a library that can do what you want. Check out the IP Helper Functions (IpHlpApi). There are calls to fetch the active UDP & TCP listens/connections/etc (GetTcpTable & GetUdpTable). These return information that can be passed to GetOwnerModuleFromTcpEntry, GetOwnerModuleFromUdpEntry. Your best bet is to look up these functions on the msdn site.

Hi,

I'm using CreateTimerQueueTimer to trigger a routine every second. Most of the time it works well, but every once in awhile it won't get triggered for upwards of 20 seconds. What could be causing it and how can I fix it? I run a couple of programs on the same machine using this call and they always stop responding at the same time due to the pause in this function.

Here's the code I'm using

HANDLE m_timerHandle;
DWORD dwTimerPeriod=1000;
HANDLE hTimerQueue = CreateTimerQueue();

BOOL success = ::CreateTimerQueueTimer(&m_timerHandle,hTimerQueue,(WAITORTIMERCALLBACK)TimerRoutine,this,dwTimerPeriod,dwTimerPeriod,WT_EXECUTEDEFAULT);

static SYSTEMTIME now2;

VOID CALLBACK TimerRoutine(PVOID lpParam, BOOLEAN TimerOrWaitFired)
{
	int nTime=getSecondsSinceTime(now2);
		if(nTime>=2)
			wc_logError("timerroutine slow!!! - %d\n",nTime);
	
	bCalcQuoteDelay=true;
	bLogStatus=true;
	::PostMessage(AfxGetApp()->m_pMainWnd->GetSafeHwnd(), WM_QUEUE_TIMER, NULL,NULL);
	
	GetLocalTime(&now2);
}

Thanks in advance!

Given that the documentation specifically states 'These threads are subject to scheduling delays, so the timing can vary depending on what else is happening in the application or the system.', if your need is timing-critical, you may want to find another means of triggering events.

How to insert seperators in Toolbar (MFC CS 2005)

I can create spaces between bitmaps on Toolbar, but how can I create seperators or grouped bitmaps that might look like as if they have seperators between grouped bitmaps?

It is possible to do it in the resource editor by "dragging" each button image to create the separator, but I find it easier to do it manually in the resource text file :

for example if you have this toolbar:

ITB_STANDARD_TOOLBAR TOOLBAR  18, 16
BEGIN
    BUTTON      ID_FILE_NEW
    BUTTON      ID_FILE_OPEN
    BUTTON      IDM_FILE_SAVE
    BUTTON      IDM_EDIT_CUT
    BUTTON      IDM_EDIT_COPY
    BUTTON      IDM_EDIT_PASTE
END

you can add a SEPARATOR statement where you want to separate between groups:

ITB_STANDARD_TOOLBAR TOOLBAR  18, 16
BEGIN
    BUTTON      ID_FILE_NEW
    BUTTON      ID_FILE_OPEN
    BUTTON      IDM_FILE_SAVE
    SEPARATOR
    BUTTON      IDM_EDIT_CUT
    BUTTON      IDM_EDIT_COPY
    BUTTON      IDM_EDIT_PASTE
END

Thats what I have now, thats equivalent to creating space between bitmaps. What I actually want to do is create a vertical line type of seperator somehow to identify sepearte bitmaps as seperate groups.

isn't this regulated by the "theme" of the application or OS ?

I just create a default application on VS2008 (with feature pack) and the separators are display as "vertical bars"

How to load 2 tool bars in Main Frame (MFC)

Software200726-Jan-10 4:49

26-Jan-10 4:49

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
	if (CMDIFrameWnd::OnCreate(lpCreateStruct) == -1)
		return -1;	
	
	if (!m_wndToolBar.Create(this) ||(
		!m_wndToolBar.LoadToolBar(IDR_MAINFRAME) )) //This load MainFRAME TOOLBAR
	{
		TRACE0("Failed to create toolbar\n");
		return -1;      // fail to create
	}

.......
Above works for one toolbar...
This will load the Main Frame tool bar, How do I load another toolbar next to it, I have (IDR_MAINFRAME2) as another smaller tool bar that i would like to have loaded next to the first one when I launch my app?

Thanks

Did you Create (in the resources and in the code) the second toolbar ?

After that, placing toolbars side by side, see this :

I think you need to read the documentation in the link I gave you earlier. You will need to create a Printer device context and then display your data on that. It is not quite as simple as saying 'print' and expecting the dialog to magically appear on the printer.

creating methods/functions in a seperate file

benjamin yap26-Jan-10 4:01

Hi all, i am very very new to c++ hope u guys can pardon me.

I have a file called "newclass.h" which declares a few methods.

//newclass.h, the specification file for the class NewClass

#ifndef _NEWCLASS_H
#define	_NEWCLASS_H
#include <string>

using namespace std;

class NewClass  {
public:

 string symbol; //variable to store the symbol (e.g.: Nasdaq)
 double lastTrade; //variable to store the last traded value
 double changeValue(); //variable to store the change in value
 double changePercentage(); //variable to store the change in percentage

   //function to get the respective values
   //the word const at the end of the member functions specify that these functions cannot modify the member variables of a variable
   void getDow(string symbol, double, double, double) const;
   void getNasdaq(string symbol, double, double, double) const;
   void getSP_500(string symbol, double, double, double) const;
   void getFTSE_100(string symbol, double, double, double) const;
   void getDAX(string symbol, double, double, double) const;
   void getNikkei_225(string symbol, double, double, double) const;
   void getHang_Seng(string symbol, double, double, double) const;
   void getStraits_Times_Index(string symbol, double, double, double) const;
};
#endif

and the other file i have is "newclass.cpp"

//newclass.cpp, the implementation file
#include <iostream>
#include "newclass.h"

using namespace std;

how do i continue writing the main function of the method in newclass.cpp

thanks

You seem to be really confused about a lot of basic concepts in C++. I strongly suggest you start by reading a book (from the begining) about the C++ language first.

Re: creating methods/functions in a seperate file

Maximilien26-Jan-10 4:28

Maximilien

something like :

void NewClass::getDow(string symbol, double value1, double value2, double value3) const
{
// ... do the code to get the Dow values for the supplied symbol.
}

use the same pattern for the other methods.

Since I do not know what the 3 double variables are, I simply called them value1, value2, value3; I assume that they really mean something; and if they are "returned" values (i.e. variables that you will assign something to them), you better make them either references (prefered) or pointers.

good luck.
